AndrewF,
I'd like to know how you wired up your CLOCK IN jack.
The only sync mods i can find are for a 12ppqn input, whatever that means.
It would be nice to slave this to one of my sequencer clocks._________________DRONEGOAT

Hi
my solution was typically brutal (see schematic), it worked but didn't solve the 12ppqn issue.
I have plenty of pulse divider type modules in my synths so it was no problem to have a fast clock for the dr-110 and divide that down for other modules and everything remained in sync.

My dr-110 is now a tt-110. An unholy crossbreed of a $3 record player, a few chunks of wood and half a dr110. Nothing is sacred in my workshop
The cpu board is dead and gone. Each voice has its own trigger, haven't got around to doing the trigger for clap yet but i think i know what to do. Each voice is triggered by a microswitch. The cct is based on this one by Tom Bugs, except I changed the .47u/20k combination to components I had plenty of.
The input needs to go to ground to get a trigger, easy with microswitches. Less easy with trigger signals. You could try the transistor design I added to the pic below or something like a 4016 or 4066 cmos will do a good job too. The inverters in the schematic below are a 40106.

that is insane!!
I like how it's a physical loop,. it reminds me of Pierre Bastien.
According to technotoys.com, if 1ppqn is quarter notes then 12 ppqn is 32nd note triplets.
I usually use my tr 606 as a master clock, so I'm dealing with 16th notes.
There are 48 32nd note triplets in a measure so I need a way to multiply my 606 clock by 3.
Does that make sense?
Is there such a thing as a multiplier?
Otherwise I'd have to build a master clock, clock divider that can divide by 3, and add a clock input to my 606.

EDIT: I've since learned that ppqn stands for "pulses per quarter note."
Reading back over this sounds like gibberish now._________________DRONEGOATLast edited by j.dilisio on Mon Feb 15, 2010 8:19 am; edited 1 time in total

So the dr-110 runs at half the speed of a tr-606. This seems like a pretty simple fix,. and cheap too.
I just enquired about a dr-110 sync kit from acidlab.de and they want 50 euros plus shipping/customs.
$4 in parts is much more doable._________________DRONEGOAT

I did the Sync24 mod to my DR-110 with poor results.
First I tried using a 74HCT74, but the output clock keep randomly jumping between 24ppqn and 12ppqn.
Then I replaced the 74HCT74 by a CD4013, now I got perfect 12ppqn output, but the clock starts 1ppqn behind, so the DR-110 is shifted a bit from my other gear.
I ended adding a direct clock input to the DR-110 and generating the 12ppqn with a VST plugin._________________Sebo

I am new to diy and have been working on DR110 mod. I have successfully implemented a lot of the pitch and filter mods, but have a sort of basic question regarding individual outs. Can I just add 2 wires from each output point, one going to a 1/4" out jack and the other to a volume pot? Is there a need for a mixer or opamp? Thanks so much for tolerating my ignorance.

Hey Richard,
Thanks for the reply. I've been through that post and done a lot of the mods that Dan Lavin and others have done, but my question is probably more simple than you think. Say I have isolated the bass drum and am sending it's audio out from the appropriate red dot. Can I just solder a wire there that goes to a pot, then to an output jack, or do I need to get involved with a mixer and op amps, as Dan did? As you may be able to tell, I am new to the DIY electronics scene. Thanks so much for any and all help.
